Antioxidant (AO) Assay:

An in vitro bioassay that measures the total anti-oxidant capacity ofany one of the ingredients, combination of ingredients, or compositionshaving said combinations disclosed in the specification. The assayrelies on the ability of antioxidants in the sample to inhibit theoxidation of ABTS® (2,2′-azino-di-[3-ethylbenzthiazoline sulphonate]) toABTS®.+ by metmyoglobin. The antioxidant system of living organismsincludes enzymes such as superoxide dismutase, catalase, and glutathioneperoxidase; macromolecules such as albumin, ceruloplasmin, and ferritin;and an array of small molecules, including ascorbic acid, α-tocopherol,β-carotene, reduced glutathione, uric acid, and bilirubin. The sum ofendogenous and food-derived antioxidants represents the totalantioxidant activity of the extracellular fluid. Cooperation of all thedifferent antioxidants provides greater protection against attack byreactive oxygen or nitrogen radicals, than any single compound alone.Thus, the overall antioxidant capacity may give more relevant biologicalinformation compared to that obtained by the measurement of individualcomponents, as it considers the cumulative effect of all antioxidantspresent in plasma and body fluids. The capacity of the antioxidants inthe sample to prevent ABTS oxidation is compared with that of Trolox, awater-soluble tocopherol analogue, and is quantified as molar Troloxequivalents. Anti-Oxidant capacity kit #709001 from Cayman Chemical (AnnArbor, Mich. USA) can be used as an in vitro bioassay to measure thetotal anti-oxidant capacity of each of any one of the activeingredients, combination of ingredients, or compositions having saidcombinations disclosed in the specification. The protocol can befollowed according to manufacturer recommendations. The assay relied onantioxidants in the sample to inhibit the oxidation of ABTS®(2,2′-azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS®.+ bymetmyoglobin. The capacity of the antioxidants in the sample to preventABTS oxidation can be compared with that Trolox, a water-solubletocopherol analogue, and was quantified as a molar Trolox equivalent.

Mushroom Tyrosinase Activity Assay:

In mammalian cells, tyrosinase catalyzes two steps in the multi-stepbiosynthesis of melanin pigments from tyrosine (and from thepolymerization of dopachrome). Tyrosinase is localized in melanocytesand produces melanin (aromatic quinone compounds) that imparts color toskin, hair, and eyes. Purified mushroom tyrosinase (Sigma) can beincubated with its substrate L-Dopa (Fisher) in the presence or absenceof each of the active ingredients, any one of the combination ofingredients, or compositions having said combinations disclosed in thespecification. Pigment formation can be evaluated by colorimetric platereading at 490 nm. The percent inhibition of mushroom tyrosinaseactivity can be calculated compared to non-treated controls to determinethe ability of test ingredients or combinations thereof to inhibit theactivity of purified enzyme. Test extract inhibition was compared withthat of kojic acid (Sigma).

Using Colorimetric DrugDiscovery kits from BioMol International for MMP3 (AK-400) and MMP-9(AK-410), this assay is designed to measure protease activity of MMPsusing a thiopeptide as a chromogenic substrate(Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC2H5)5,6. The MMP cleavagesite peptide bond is replaced by a thioester bond in the thiopeptide.Hydrolysis of this bond by an MMP produces a sulfhydryl group, whichreacts with DTNB [5,5′-dithiobis(2-nitrobenzoic acid), Ellman's reagent]to form 2-nitro-5-thiobenzoic acid, which can be detected by itsabsorbance at 412 nm (c=13,600 M-1 cm-1 at pH 6.0 and above 7). Theactive ingredients, any one of the combination of ingredients, orcompositions having said combinations disclosed in the specification canbe assayed.

Cyclooxygenase (COX) Assay:

An in vitro cyclooxygenase-1 and -2 (COX-1, -2) inhibition assay. COX isa bifunctional enzyme exhibiting both cyclooxygenase and peroxidaseactivities. The cyclooxygenase activity converts arachidonic acid to ahydroperoxy endoperoxide (Prostaglandin G2; PGG2) and the peroxidasecomponent reduces the endoperoxide (Prostaglandin H2; PGH2) to thecorresponding alcohol, the precursor of prostaglandins, thromboxanes,and prostacyclins. This COX Inhibitor screening assay measures theperoxidase component of cyclooxygenases. The peroxidase activity isassayed colorimetrically by monitoring the appearance of oxidizedN,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD). This inhibitorscreening assay includes both COX-1 and COX-2 enzymes in order to screenisozyme-specific inhibitors. The Colormetric COX (ovine) Inhibitorscreening assay (#760111, Cayman Chemical) can be used to analyze theeffects of each of the active ingredients, any one of the combination ofingredients, or compositions having said combinations disclosed in thespecification on the activity of purified cyclooxygnase enzyme (COX-1 orCOX-2). According to manufacturer instructions, purified enzyme, hemeand test extracts can be mixed in assay buffer and incubated withshaking for 15 min at room temperature. Following incubation,arachidonic acid and colorimetric substrate can be added to initiate thereaction. Color progression can be evaluated by colorimetric platereading at 590 nm. The percent inhibition of COX-1 or COX-2 activity canbe calculated compared to non-treated controls to determine the abilityof test extracts to inhibit the activity of purified enzyme.

Lipoxygenase (LO) Assay:

An in vitro lipoxygenase (LO) inhibition assay. LOs are non-hemeiron-containing dioxygenases that catalyze the addition of molecularoxygen to fatty acids. Linoleate and arachidonate are the mainsubstrates for LOs in plants and animals. Arachadonic acid may then beconverted to hydroxyeicosotrienenoic (HETE) acid derivatives, that aresubsequently converted to leukotirenes, potent inflammatory mediators.This assay provides an accurate and convenient method for screeninglipoxygenase inhibitors by measuring the hydroperoxides generated fromthe incubation of a lipoxygenase (5-, 12-, or 15-LO) with arachidonicacid. The Colorimetric LO Inhibitor screening kit (#760700, CaymanChemical) can be used to determine the ability of each of the activeingredients, any one of the combination of ingredients, or compositionshaving said combinations disclosed in the specification to inhibitenzyme activity. Purified 15-lipoxygenase and test ingredients can bemixed in assay buffer and incubated with shaking for 10 min at roomtemperature. Following incubation, arachidonic acid can be added toinitiate the reaction and mixtures incubated for an additional 10 min atroom temperature. Colorimetric substrate can be added to terminatecatalysis and color progression was evaluated by fluorescence platereading at 490 nm. The percent inhibition of lipoxyganse activity can becalculated compared to non-treated controls to determine the ability ofeach of the active ingredients, any one of the combination ofingredients, or compositions having said combinations disclosed in thespecification to inhibit the activity of purified enzyme.

Elastase Assay:

EnzChek® Elastase Assay (Kit# E-12056) from Molecular Probes (Eugene,Oreg. USA) can be used as an in vitro enzyme inhibition assay formeasuring inhibition of elastase activity for each of the activeingredients, any one of the combination of ingredients, or compositionshaving said combinations disclosed in the specification. The EnzChek kitcontains soluble bovine neck ligament elastin that can be labeled withdye such that the conjugate's fluorescence can be quenched. Thenon-fluorescent substrate can be digested by elastase or other proteasesto yield highly fluorescent fragments. The resulting increase influorescence can be monitored with a fluorescence microplate reader.Digestion products from the elastin substrate have absorption maxima at˜505 nm and fluorescence emission maxima at ˜515 nm. The peptide,chloromethyl ketone, can be used as a selective, collective inhibitor ofelastase when utilizing the EnzChek Elastase Assay Kit for screening forelastase inhibitors.

Oil Control Assay:

An assay to measure reduction of sebum secretion from sebaceous glandsand/or reduction of sebum production from sebaceous glands can beassayed by using standard techniques known to those having ordinaryskill in the art. In one instance, the forehead can be used. Each of theactive ingredients, any one of the combination of ingredients, orcompositions having said combinations disclosed in the specification canbe applied to one portion of the forehead once or twice daily for a setperiod of days (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, ormore days), while another portion of the forehead is not treated withthe composition. After the set period of days expires, then sebumsecretion can be assayed by application of fine blotting paper to thetreated and untreated forehead skin. This is done by first removing anysebum from the treated and untreated areas with moist and dry cloths.Blotting paper can then be applied to the treated and untreated areas ofthe forehead, and an elastic band can be placed around the forehead togently press the blotting paper onto the skin. After 2 hours theblotting papers can be removed, allowed to dry and thentransilluminated. Darker blotting paper correlates with more sebumsecretion (or lighter blotting paper correlates with reduced sebumsecretion.

Erythema Assay:

An assay to measure the reduction of skin redness can be evaluated usinga Minolta Chromometer. Skin erythema may be induced by applying a 0.2%solution of sodium dodecyl sulfate on the forearm of a subject. The areais protected by an occlusive patch for 24 hrs. After 24 hrs, the patchis removed and the irritation-induced redness can be assessed using thea* values of the Minolta Chroma Meter. The a* value measures changes inskin color in the red region. Immediately after reading, the area istreated with the active ingredients, any one of the combination ofingredients, or compositions having said combinations disclosed in thespecification. Repeat measurements can be taken at regular intervals todetermine the formula's ability to reduce redness and irritation.

Skin Moisture/Hydration Assay:

Skin moisture/hydration benefits can be measured by using impedancemeasurements with the Nova Dermal Phase Meter. The impedance metermeasures changes in skin moisture content. The outer layer of the skinhas distinct electrical properties. When skin is dry it conductselectricity very poorly. As it becomes more hydrated increasingconductivity results. Consequently, changes in skin impedance (relatedto conductivity) can be used to assess changes in skin hydration. Theunit can be calibrated according to instrument instructions for eachtesting day. A notation of temperature and relative humidity can also bemade. Subjects can be evaluated as follows: prior to measurement theycan equilibrate in a room with defined humidity (e.g., 30-50%) andtemperature (e.g., 68-72° C.). Three separate impedance readings can betaken on each side of the face, recorded, and averaged. The T5 settingcan be used on the impedance meter which averages the impedance valuesof every five seconds application to the face. Changes can be reportedwith statistical variance and significance. Each of the activeingredients, any one of the combination of ingredients, or compositionshaving said combinations disclosed in the specification can be assayedaccording to this process.

Skin Clarity and Reduction in Freckles and Age Spots Assay:

Skin clarity and the reduction in freckles and age spots can beevaluated using a Minolta Chromometer. Changes in skin color can beassessed to determine irritation potential due to product treatmentusing the a* values of the Minolta Chroma Meter. The a* value measureschanges in skin color in the red region. This is used to determinewhether each of the active ingredients, any one of the combination ofingredients, or compositions having said combinations disclosed in thespecification is inducing irritation. The measurements can be made oneach side of the face and averaged, as left and right facial values.Skin clarity can also be measured using the Minolta Meter. Themeasurement is a combination of the a*, b, and L values of the MinoltaMeter and is related to skin brightness, and correlates well with skinsmoothness and hydration. Skin reading is taken as above. In onenon-limiting aspect, skin clarity can be described as L/C where C ischroma and is defined as (a²+b²)^(1/2).

Skin Dryness, Surface Fine Lines, Skin Smoothness, and Skin Tone Assay:

Skin dryness, surface fine lines, skin smoothness, and skin tone can beevaluated with clinical grading techniques. For example, clinicalgrading of skin dryness can be determined by a five point standardKligman Scale: (0) skin is soft and moist; (1) skin appears normal withno visible dryness; (2) skin feels slightly dry to the touch with novisible flaking; (3) skin feels dry, tough, and has a whitish appearancewith some scaling; and (4) skin feels very dry, rough, and has a whitishappearance with scaling. Evaluations can be made independently by twoclinicians and averaged.

Clinical Grading of Skin Tone Assay:

Clinical grading of skin tone can be performed via a ten point analognumerical scale: (10) even skin of uniform, pinkish brown color. Nodark, erythremic, or scaly patches upon examination with a hand heldmagnifying lens. Microtexture of the skin very uniform upon touch; (7)even skin tone observed without magnification. No scaly areas, butslight discolorations either due to pigmentation or erythema. Nodiscolorations more than 1 cm in diameter; (4) both skin discolorationand uneven texture easily noticeable. Slight scaliness. Skin rough tothe touch in some areas; and (1) uneven skin coloration and texture.Numerous areas of scaliness and discoloration, either hypopigmented,erythremic or dark spots. Large areas of uneven color more than 1 cm indiameter. Evaluations were made independently by two clinicians andaveraged.

Clinical Grading of Skin Smoothness Assay:

Clinical grading of skin smoothness can be analyzed via a ten pointanalog numerical scale: (10) smooth, skin is moist and glistening, noresistance upon dragging finger across surface; (7) somewhat smooth,slight resistance; (4) rough, visibly altered, friction upon rubbing;and (1) rough, flaky, uneven surface. Evaluations were madeindependently by two clinicians and averaged.

Skin Smoothness and Wrinkle Reduction Assay with Methods Disclosed inPackman et al. (1978):

Skin smoothness and wrinkle reduction can also be assessed visually byusing the methods disclosed in Packman et al. (1978). For example, ateach subject visit, the depth, shallowness and the total number ofsuperficial facial lines (SFLs) of each subject can be carefully scoredand recorded. A numerical score was obtained by multiplying a numberfactor times a depth/width/length factor. Scores are obtained for theeye area and mouth area (left and right sides) and added together as thetotal wrinkle score.

Skin Firmness Assay with a Hargens Ballistometer:

Skin firmness can be measured using a Hargens ballistometer, a devicethat evaluates the elasticity and firmness of the skin by dropping asmall body onto the skin and recording its first two rebound peaks. Theballistometry is a small lightweight probe with a relatively blunt tip(4 square mm-contact area) was used. The probe penetrates slightly intothe skin and results in measurements that are dependent upon theproperties of the outer layers of the skin, including the stratumcorneum and outer epidermis and some of the dermal layers.

Skin Softness/Suppleness Assay with a Gas Bearing Electrodynamometer:

Skin softness/suppleness can be evaluated using the Gas BearingElectrodynamometer, an instrument that measures the stress/strainproperties of the skin. The viscoelastic properties of skin correlatewith skin moisturization. Measurements can be obtained on thepredetermined site on the cheek area by attaching the probe to the skinsurface with double-stick tape. A force of approximately 3.5 gm can beapplied parallel to the skin surface and the skin displacement isaccurately measured. Skin suppleness can then be calculated and isexpressed as DSR (Dynamic Spring Rate in gm/mm).

Appearance of Lines and Wrinkles Assay with Replicas:

The appearance of lines and wrinkles on the skin can be evaluated usingreplicas, which is the impression of the skin's surface. Silicone rubberlike material can be used. The replica can be analyzed by imageanalysis. Changes in the visibility of lines and wrinkles can beobjectively quantified via the taking of silicon replicas form thesubjects' face and analyzing the replicas image using a computer imageanalysis system. Replicas can be taken from the eye area and the neckarea, and photographed with a digital camera using a low angle incidencelighting. The digital images can be analyzed with an image processingprogram and are of the replicas covered by wrinkles or fine lines wasdetermined.

Surface Contour of the Skin Assay with a Profilometer/Stylus Method:

The surface contour of the skin can be measured by using theprofilometer/Stylus method. This includes either shining a light ordragging a stylus across the replica surface. The vertical displacementof the stylus can be fed into a computer via a distance transducer, andafter scanning a fixed length of replica a cross-sectional analysis ofskin profile can be generated as a two-dimensional curve. This scan canbe repeated any number of times along a fix axis to generate a simulated3-D picture of the skin. Ten random sections of the replicas using thestylus technique can be obtained and combined to generate averagevalues. The values of interest include Ra which is the arithmetic meanof all roughness (height) values computed by integrating the profileheight relative to the mean profile height. Rt which is the maximumvertical distance between the highest peak and lowest trough, and Rzwhich is the mean peak amplitude minus the mean peak height. Values aregiven as a calibrated value in mm. Equipment should be standardizedprior to each use by scanning metal standards of know values. Ra Valuecan be computed by the following equation: R_(a)=Standardize roughness;l_(m)=the traverse (scan) length; and y=the absolute value of thelocation of the profile relative to the mean profile height (x-axis).
